Abstract
Introduction: The definitive diagnosis of the common types of glomerular disease including FSGS (focal segmental glomerulosclerosis) and MN (membranous nephropathy) is still performed by biopsy studies, which has high risks and complications. MicroRNAs (miRNAs) can open a new horizon for the treatment and diagnosis of glomerular diseases. Objectives: In the present study, we focused on miR-217, miR-193-3p, and miR-124 expression in patients with FSGS and MN. Patients and Methods: Sixty cases (30 FSGS and 30 MN) were included based on strict criteria. A group of healthy controls were also included. The relative expression of the microRNAs was evaluated in the plasma and peripheral blood mononuclear cells (PBMCs) by quantitative real-time PCR. The association between the expression levels of microRNAs and clinicopathological parameters were also assessed. Results: There were significant differences in miR-193-3p levels between FSGS and MN group in plasma samples (P = 0.036). Furthermore, significantly decreased levels of miR-217 were observed in plasma samples of patients with NS (P = 0.026) and MN (P = 0.036) groups. Conclusion: The studied miRNAs are dysregulated in clinical samples of patients with nephrotic syndrome and they may be involved in the pathogenesis of FSGS and MN. More research is needed for understanding the relationship between these microRNAs and the pathogenesis of FSGS and MGN.
